Sensors & Test

NASA’s Goddard Space Flight Center has developed a method to collect suspicious data and analyze them without extensive costs. A common challenge in complex computer systems is the identification of unauthorized use, which can be...

Engineers at Goddard Space Flight Center have overcome limitations plaguing the satellite sector since its inception through the development of a robotic system allowing for the autonomous capture and servicing of in-orbit satellites. By...

The need for non-invasive, real-time measurement of the density and speed of sound of a liquid led to the development of an ultrasonic sensing technique based upon the reflection of ultrasound at the solid-fluid interface.

NASA has developed a method and system that provides selective access to different portions of a database by different subgroups of database users. In this system, two or more members of a given access subgroup can simultaneously edit a document accessible to each member. This database system provides...

The Pressure Sensor Mechanism is designed to measure or monitor tactile pressure. It is based on passive Radio Frequency Identification (RFID) sensor tags and is applicable to a variety of systems. As RFID sensors transmit information wirelessly, they eliminate many challenges associated with traditional wired systems such...

A temperature sensor with practically no effect at all on the temperature of the object measured has been created in the laboratory by researchers at the University of São Paulo (USP) and the University of Campinas (UNICAMP) and is awaiting a patent for commercial production.

Electron-ionized atom trapping technology is widely used in mass spectrometry and atomic clocks. The complexity of the trapping configuration operating in an ultra-high vacuum system is driven by demands for ultimate sensitivity, performance, and fundamental...
